How the leads taken in bipolar limb leads? A physiological response to a current applied to the surface of the heart that results in unnecessary stimulation like muscle contractions or tissue injury is called as microshock.

EEG may be recorded by picking up voltage difference between an active electrode on the scalp with respect to a reference electrode on the ear lobe or other part of the body. If the transmitter substance is excitatory, the receptor membrane potential increases in a positive direction. The platelet are involved in the clotting of blood. The pH meter with hydroscopic glass observes the water readily and provides best pH value. The rate at which an action potential moves down a fiber of a nerve cell or is propagated from cell to cell is called the propagation rate or conduction velocity.

The body organs could be visualized in X-ray by using the principle of energy absorption. What are tachycardia and bradycardia? For what purpose pacemaker is flectronics When the cell fires however, the outside of the cell becomes momentarily negative with respect to the interior. What is meant by Demand Pacemaker? Give the uses of silver-silver chloride electrode.

The phenomenon of application of an electrical shock to resynchronize the heart is known as counter shock. The electrocardiogram is a graphic recording or display of the time variant voltage display produced by myocardium during cardiac cycle. The hydrogen electrode is also called a reference electrode.

It requires open chest minor surgery to place the circuit. Permanent record is available.

List the factors to be considered for designing medical instrument. What is the use of biphasic D. Ventricular fibrillation can be converted into a more efficient rhythm by applying a high energy shock to the heart.

Heart rate slower than 60 BPM is called bradycardia. Each cell consists of a centrally located nucleus cell core surrounded by the cytoplasm cell body. You can here download question papers fr The online recorders are directly connected with the input.

The nucleus is separated from the cytoplasm by a nuclear membrane. For what purpose isolation amplifier is used? A group of cells of the same type is called tissue.

Microelectrodes are used to measure the bioelectric potential near or within a single cell. The SEN is recently developed electron microscope.

Compare external pacemaker and internal pacemaker. It is a piece of platinum wire embedded in an insulating glass holder with the end of wire.

Therefore one can get the live recording at the spot itself. Acoustic events of the heart can be divided into two categories as heart sounds and murmurs. About 75 percent of cell is water. State the principle by which body organs could be visualized by radioisotope method. What are graded potentials? It is a special- x-ray imaging technique through which high contrast can be obtained. Heart sounds and murmurs are usually characterized by three physical properties. Discuss briefly about cell. Explain the working of single channel ECG telemetry system.

What is the need for earthing of medical instruments? The diffusion and drift processes give rise to membrane potential.
